The present invention provides a system, method and apparatus for providing variable rate application of applicants to discrete field locations. According to a first preferred embodiment, the present invention includes a control device having software modules to allow for the execution of irrigation and chemical spray patterns according to specific prescriptions for each crop being sprayed. According to further preferred embodiments, the control device may use data from a variety of image sensors to create a selective, variable rate application of applicants. Using the imaging data, the system of the present invention may use a primary applicant system to broadly deliver a first selected application (e.g. water or the like) and use a separate system to deliver targeted applicants for specific plants or areas of a given field.

A localized product injection system includes a composite boom tube having a carrier fluid passage within a tube body, and at least one injection product passage within the tube body isolated from the carrier fluid passage. A plurality of port stations are provided at locations along the tube body. Each of the port stations includes a carrier fluid outlet port and at least one injection product outlet port. A localized injection interface is coupled at a port station. The injection interface includes a carrier fluid input coupled with the carrier fluid outlet port, and at least one injection product input coupled with the at least one injection product outlet port. The injection interface includes at least one throttling element in communication with the at least one injection product input, a mixing chamber, and an injection port configured for localized coupling and injection to a product dispenser.

The present invention relates to a spraying system for an agricultural sprayer, comprising a spray boom having a nozzle holder comprising a body housing a spray product inlet duct configured to be supplied with spray product, a nozzle for said product comprising an outlet orifice for said product and configured to be supplied with product via the inlet duct and to convey said product towards said outlet orifice, a vibration sensor; said boom being configured to spray product through said nozzle; said sensor being configured to measure the vibrations of the body, said spraying system further comprising a computing unit configured to compare the vibration measurement with a reference signal to determine the clog state of said nozzle.

A system comprising a boom, a plurality of nozzles disposed along the boom, a light disposed on the boom to illuminate a spray pattern from at least one nozzle, a camera disposed on the boom to capture a first image of a spray from the at least one nozzle at a first time and a second image of no spray from the at least one nozzle at a second time, and a processor to calculate a difference between the first time and second time to determine a pulse width modulation of the at least one nozzle.

Method for generating a control signal for a smart spraying device with at least one individual spray nozzle, and a method for controlling a smart spraying device, using PWM and field data relating to a vegetative indicator for providing an improved adaptive application of products onto an area to be treated.

A method of calibrating dosing valves of a sprayer system of an agricultural implement comprises initiating calibration by filling a calibrating tube with fluid having a fluid from an auxiliary tank of the sprayer system, measuring a volume of the fluid filled into the calibration tube, pumping the fluid in the calibration tube to the dosing valves to calibrate the dosing valves with respect to flow characteristics of the fluid with the dosing valves being capable of a high fluid flow rate to a low fluid flow rate ratio of at least 100:1 for the fluid. The method also includes pumping, during a pump from concentration tank mode, the fluid in the concentration tank to the dosing valves and then to a mixing apparatus with the fluid to be mixed with a carrier fluid from a primary tank of the sprayer system.
